[0002] Fertilization is an important part in agricultural planting. Fertilizer can provide the necessary nutrients for plant growth, improve soil fertility and soil structure, increase crop yield and quality, and enhance plant resistance. After fertilization, soil covering is required, mainly to cover the fertilizer, reduce fertilizer volatilization, maintain soil moisture, and create a good soil environment for plant growth. Due to the different fertilizers, the precautions for soil covering are also different. For volatile fertilizers, the soil covering operation should be quick. These fertilizers will cause ammonia volatilization if exposed to the air for too long, reducing fertilizer efficiency. In actual planting, if crops are already growing, it is necessary to use tools such as shovels to cover the soil. Due to the fast speed, it is easy to cause damage to the crops in the process of covering the soil, affecting the growth of crops. Utility Model Content

Fertilizer is placed in the pit below the outer shell 1, and the outer shell 1 is continuously moved. As the soil inside the outer shell 1 increases, excess soil will fall down from the other side of the outer shell 1, and the fallen soil will cover the fertilizer. When the outer shell 1 continues to move and continues to place fertilizer in the pit left by the outer shell 1, the fertilizer can be quickly covered with soil after fertilization. Connecting seats 11 are provided on both sides of the outer shell 1, and the connecting seats 11 are fixedly connected to the outer shell 1. The two connecting seats 11 are symmetrical to each other. The outer side of the connecting seat 11 is rotatably connected to a movable rod 12, and the movable rod 12 and the connecting seat 11 are damped for rotation. By rotating the movable rod 12, the angle of the movable rod 12 can be adjusted, which is convenient for adjusting the dragging of the outer shell 1. The ends of the two movable rods 12 are connected by a connecting rod 121, and the two ends of the connecting rod 121 are fixedly connected to the two movable rods 12 respectively. The connecting rod 121 is perpendicular to the movable rod 12, and the connecting rod 121 does not contact the outer shell 1. A handle 13 is provided on the side of the connecting rod 121 away from the outer shell 1.

A plurality of fixed rods 15 and a plurality of fixed rods 2 16 are provided on the inner side of the outer shell 1. The fixed rod 15 and the fixed rod 2 1 Both ends of 6 are fixedly connected to the inner wall of the outer shell 1, and several fixing rods 15 are arranged at equal distances, and several fixing rods 2 16 are arranged at equal distances. When the soil moves inside the outer shell 1, the soil will pass through the fixing rods 15 and the fixing rods 2 16. The purpose of dispersing the soil can be achieved through the fixing rods 15 and the fixing rods 2 16, which is beneficial to improving the uniformity and air permeability of the covering soil. Both sides of the outer shell 1 are slidably connected with a movable plate 2, one side of the movable plate 2 is in contact with the outer side of the outer shell 1, and the bottom of the movable plate 2 is provided with several ears 21, the top of the ear 21 is fixedly connected to the movable plate 2, and several ears 21 are equidistantly distributed. A roller 211 is provided on the inner side of the ear 21, and the roller 211 is rotatably connected to the ear 21. When the outer shell 1 is inserted into the soil, several rollers 211 will be located on the soil on both sides of the outer shell 1. Through the contact between the several rollers 211 and the soil, the movable plate 2 will be parallel to the surface of the soil, thereby ensuring that the outer shell 1 is in an inclined state. Several fixed plates 17 are provided on both sides of the outer shell 1. The fixed plates 17 are fixedly connected to the outer shell 1. The fixed plates 17 and the movable plates 2 are connected by springs 171. The springs 171 can prevent the rollers 211 from interfering with the sinking depth of the outer shell 1. By moving the outer shell 1 in the soil, pits can be dug in the soil while covering the fertilizer applied in the pits with soil, thereby achieving the purpose of quickly sealing the fertilizer and reducing the volatilization of the fertilizer. At the same time,The plurality of fixing rods 15 and the plurality of fixing rods 2 16 can disperse the soil as it passes through the interior of the outer shell 1, which is beneficial to improving the uniformity and air permeability of the covering soil.

[0025] The working principle and usage process of the present invention are as follows: when in use, one side of the outer shell 1 needs to be inserted into the soil first and pushed along the desired fertilization route, so that the soil can be dug into the interior of the outer shell 1, and there will be pits on the soil surface. Fertilizer is placed in the pit below the outer shell 1, and the outer shell 1 is continuously moved. As the soil inside the outer shell 1 increases, excess soil will fall down from the other side of the outer shell 1, and the fallen soil will cover the fertilizer. When the outer shell 1 continues to move and fertilizer is continuously placed in the pit left by the outer shell 1, the fertilizer can be quickly covered with soil after fertilization. At the same time, when the soil passes through the interior of the outer shell 1, the soil can be loosened by a number of fixing rods 15 and 2 fixing rods 16.
